<em><strong><span style="color: #ff0000;">SERIALIZATION</span></strong><br /> Serialization is the process of turning an object in memory into a stream of byte so you can do stuff like store it on disk or send it over the network.</em><em> <p>A C# object can be serialized to XML as specified-<br /> ? To use Serialization in xml we need XmlSerializer class.<br /> ? This class is derived from System.Xml.Serialization.<br /> ?
